python - Create empty conda environment

Question

I can create a new conda environment, with program biopython with this:

conda create --name snowflakes biopython

What if I do not want to install any program? It seems I can not do that:

? conda create --name tryout
Error: too few arguments, must supply command line package specs or --file

You can specify one or more default packages to install when creating
an environment.  Doing so allows you to call conda create without
explicitly providing any package names.

To set the provided packages, call conda config like this:

    conda config --add create_default_packages PACKAGE_NAME

Answer 1

You can give a package name of just "python" to get a base, empty install.

conda create --name myenv python
conda create --name myenv python=3.4
